ABSTRACT:
A cartridge filter element for installation in a plenum of a filtration housing that receives a dirty air flow and cleans that flow by flow passage through a filter material or media of the cartridge filter element, with the cleaned air then passed out of a discharge end of the cartridge filter element and vented through a clean air discharge line. The cartridge filter element includes a section of the filter material that is formed, as by rolling, into an outer cylinder and includes bands fitted therearound for maintaining its cylindrical shape. An access door, that is preferably a flat plate having four corners, is centered across the outer cylinder rear end to extend at a right angle therefrom to close off that cylinder rear end. The access door functions as both the cylinder rear end cap and provides for connection over a filter access opening that is formed into the filtration housing that receives the cartridge filter element installed therein to positioned the filter element across the filtration housing dirty air plenum. The outer cylinder also includes a forward end seal that is formed from an appropriate seal material and is maintained across the cylinder forward end for fitting, in seal engagement, into an air discharge port or opening of the filtration housing that is for discharging cleaned air into a clean air outlet. An inner core, that is preferably formed from a section of porous metal, such as steel, is rolled into a cylinder, and is longitudinally centered in the outer cylinder, between the access door and end seal to provide an open area between the opposing outer and core surfaces as a clean air plenum for distributing air over the inner cylinder or core porous surface that is pulled into to core and passes therefrom into the clean air outlet.
